woo'L-BURRING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 317,638, dated May 12,1885.

(N0 model.)

To @ZZ whom, it may concern:

Be it known that I, CALVIN L. Gonniinuof the city and county of New York, in the State of New York, have invented a certain new and useful Improvement in IVool Burring Machinery, of which the following is a specification.

There are in all wool small cots or knots which are too small for the wool-picker to open, and which are seen upon the workers of a wool-card. These cots, knots, or locks are often hard and difficult to open, and when they come between the carding-surface and the Workers they bend down or injure the cardingsurface or card-clothing, and the ber of which they are composed is rubbed off and shortened instead of the cots or knots being opened. This mode of working impairs the effectiveness of the card-clothing and makes short stock of all the cots or knots.

The object of my invention is to effect the thorough opening and loosening of all such cots or knots as are so small that they pass through the picker before the wool is carded, whereby I better prepare the wool for carding and enable finer and softer card-clothing to be used without danger of its being injured.

rIhis invention may be embodied in a separate machine through which the wool is passed after it leaves the picker, or in an attachment to be placed at the delivery side of thepicker, or in an attachment to a cardingengine, in which case the wool would be passed through the attachment before it is presented to the cards. Y

rIhe invention consists in a burr-cylinder having iianges, the inner sides of which are oblique to the axis of the cylinder, and having its surface composed of separate and independent toothed rings and interposed packing-rings secured between the oblique sides of said flanges, and by them held in oblique positions on the cylinder. Vhen thus constructed, the toothed rings do not rotate in planes directly at right angles to the axis of the cylto cause their teeth to cover every point in a surface in contact with the cylinder.

rIhe invention also consists in the combination,with a burncylinder composed of toothed rings7 of a toothed cotter-cylinder arranged adjacent to the burrcylinder, and means for rotating said cylinders in directions reverse to each other. In thelabove combination the teeth of both cylinders are hooked or inclined, and the teeth of the burr-cylinder project for- Ward and the teeth of the cotter-cylinder rearward relatively to their directions of rotation, and the surface-velocity of the cotter-cylinder is very much less than that of the burrcylinder. All the wool which is below the surface of theV burr-cylinder will be carried on. untouched by the cotter-cylinder to the stripper, but the cots or knots which are upon the surface of the burrcylinder will be opened by the cotter-cylinder. I also combine with the burr and cotter cylinders, above described, a single brush, card-tumbler, or other stripper for stripping the wool from both cylinders.

The invention also consists in the combination, with a burr-cylinder and hook-toothed feed and holding rolls, of a wipe-and-pressure roll arranged to strip or wipe the Wool from one of the feed-rolls and to press the wool onto the burr-cylinder, and having wings or portions of a material softer than the teeth of the burr-cylinder, so that said wings or portions will not injure the teeth of the burr-cylinder by contact with them, and mechanism for rotating said cylinder and rolls. The wipeand -pressure roll may with advantage be made of a grooved or slotted bar and wings of sole-leather inserted therein.

The invention also consists in other combinations of parts, hereinafter described and claimed.

In the accompanying drawings, Figure I represents a side view of an attachment for a cardingmachine embodying my invention. Fig. 2 represents a vertical section thereof. Fig. 8 represents a side view of myimproved cylinder;` and Fig. t represents a vertical section of an attachment for a wool-picker, also embodying my invention.

Similar' letters of reference designate corresponding parts in all the figures.

Referring first to Figs. I and 2, A A designate upper and lower feed-rolls. B designates the burr-cylinder. C designates a wipe-andpressure roll,which rotates in close proximity to the upper feed-roll and burr-cylinder.

rIhe feed-rolls (see Figs. 2 and 3) have their IOO e classe tallic packing-rings interposed between them to hold them at a proper distance apart. The teeth of the two feed-rolls are here shown as hooked, and the teeth of the lower roll, A', project or are inclined rearward, or in a direction the reverse of that in which said roll rotates. The feed-rolls therefore have a very strong hold on the wool and enable the burr-cylinder to pierce through and comb apart the cots, knots, or matted locks while the wool is firmly held back by the feed-rolls. The wool, firmly held, is drawn down into the burr-cylinder bclowits surface,while all refuse remains on the surface. The teeth of the feed-rolls should be very rigid and strong, to enable them to hold the wool against the pull of the burr-cylinder, as on this largely depends the efficiency of the burr-cylinder. The feed-rolls may bc about two and one-half inches in diameter, and are made with `from six to ten toothed rings to the inch. Feedrolls made ot' card-fillet soon become bent or bruised, and the wool is held at some points, while at others it is not held. The burrcylinder therefore receives the wool unevenly, and its usefulness is greatly impaired. These metallic ring feed-rolls are mounted in boxes made according to 'Letters Patent No. 45,034, dated November l5, 1864- that is, the bearings of the upper roll are adjustable in the arc of a circle concentric to the axis of the lower roll.

Although the burr-cylinder B may beof any desired construction, I prefer to construct it of metal strips and wood combined on a metal shaft, as shown and described in Letters Patent No. 49,625, granted to C. L. Goddard, August 29, 1865.

The. cylinder B has upon it metallic rings b, provided with hooked teeth and metallic packing-rings b', interposed between the toothed rings, as shown in Fig. 3. The packing-rings may be made by cutting them out ot' sheet i metal; but as this requires a great deal of stock and entails waste, I prefer to make the packing-rings out of iron wire. Bound wire ,may be rolled square, or it may be rolled down flat to tit the faces of the toothed rings. The wire is then bent to the circle desired but a little less in size, either in a machine made for the purpose or by winding it on a mandrel in alathe. The wire is then wound upon a cylinder the size of the one on which the rings are to be used, and-the coil is cut longitudinally of the cylinder, the ends of the cut pieces are brazed together', and the rings are complete. These packing-rings are solid and smooth and admit of narrow toothed rings being used. They are very much stronger than sheet-metal rings.

It is desirable in opening close, hard, cotted, or matted, or felted stock that the rings of the burr cylinder should not rotate in planes directly at right angles to the axis of the cylinder, but should vary from such planes sufficiently to cover every point in a contactsurface as the cylinder rotates. This result I accomplish by setting the flanges or heads B of the cylinder with their inner faces slightly oblique to the axis of the cylinder, as shown in Fig. 3, for example, about an eighth of an inch out of planes at right angles to the axis of the cylinder. Then all the toothed rings held between the iianges will have a corresponding amount of Obliquity.

After the heads or flanges B of the cylinder have been fitted I remove them and chuck them in a lathe, and turn off their inner faces to give them the desired degree of Obliquity. The two heads or fianges are then set opposite to each other on the cylinder so that their faces will be parallel, and all the toothed rings will then be oblique to the axis of the cylinder.

It is obvious that a cylinder with the toothed rings set in this way will be very effective, and will do much better work than where the rings turn in planes exactly at right angles to the axis of the cylinder.

The burr-cylinders in different machinesl may vary from th ree and one-half to fourteen inches in diameter, and may make about one hundred revolu-tions per minute.

p The wipe-and-pressure roll C may be com` posed of an iron bar or shaft grooved or slotted longitudinally at c, and having ribs or wings c' of sole-leather inserted within the grooves, with the edges of the wings either plane or serrated. The grooves c are made smaller at the surface of the bar or shaft than at the bottom, and the wings c are drawninto them from one end of the bar or shaft.

The wipe-and-pressure roll C runs close enough to the upper feed-roll, A, to strip it, wiping against the backs of the teeth, and close enough to the burr-cylinder to cause it to take up on the points of its teeth any cots or felted or matted locks that have not been hooked upon them by the hold of the feedrollers. The revolution or rubbing of the sole-leather wings c on the teeth ofthe upper feed-roll while wiping off the stock tends to produce the serration of the edges of the wings; but this scrration improves the working of the wipe-and-pressure roll as the wings move far- Instead of the wines c/ beine` made of sole- IOO IIO

leather, they may be of copper, brass, or other material considerably softer than the steel teeth of the feed-roll and burr-cylinder.

D designates the beater or guard, which is journaled in bearings above the burr-cylinder B.' The beater or guard may be a hollow casting with the heads cast in and shafts inserted in the heads; or it may consist of a piece of ordinary gas -pipe having headed journals welded to the ends thereof'. The beater or guard isslotted or grooved lengthwise, either spirally or in straight lines, and wings or blades d are inserted and fastened in the slots or grooves, so as to have a projection of about threeeighths of an inch. The beater or guard is used from three and one-half to five inches in diameter, according to the diameter of the i alf/,ssa s burr-cylinder with which it is to be combined, and it should rotate about two hundred and fifty turns a minute.

` By the combined action of the feed-rolls and burr-cylinder the loosened and opened wool is drawn down into or between the teeth of the burr-cylinder, while all refuse matter left upon the surface is whipped into the burrbox by the guard or beater D. After the burrs and other extraneous matters have been knocked off into the burr-box by the guard D the wool is carried by the rotation of the burr-cylinder to the supplemental metallic hook-toothed cylinder E, which I term a cotter cylinder.77 The openedv wool which is below the surface of the burr-cylinder will pass by untouched by the teeth of the cottercylinder, but the cots or matted or felted knots or locks will be caught by the teeth of the cottercylinder, and as the teeth are hooked and strong the cots, knots, or locks will be opened and made ready for the after oarding processes. The Cotter-cylinder may be of any construction adapted to its use; but I propose to make it like the burr-cylinder, with oblique heads or iiauges and toothed rings b, with interposed metallic packing-rings. The Cotter-cylinder is driven at about ten revolutions per minute backward, or in the reverse direction to the burr-cylinder.

F designates the tuiiiibler or first card, which is arranged close enough to the burr-cylinder B and Cotter-cylinder E to strip the wool from both of them.

The burr-cylinder B and cotter-cylinder E,

.by reason of the toothed rings and their different speeds, card, tease, unravel, unroll, and loosen all unopened stock which would otherwise pass to the cards, and bend, bruise, and injure the cards to such an extent as to greatly impair their eiticiency.

The feed-rolls, wipe-and-pressure roll, burrcylinder, Cotter-cylinder, guard, and tumbler may all be operated to give them the desired speeds by any suitable mechanism. The mechanism here shown, and which I will now describe is well adapted for the purpose.

The burr-cylinder B is driven by a belt, e, from the main cylinder of the carding-engine, passing over a pulley, e, on the journal of said burr-cylinder.` The belt e passes over and moves iu contact with a pulley, e2, ou the tumbler F, and so rotates the latter. The beater or guard D is driven by a belt, f, pass ing over a pulley, f', and deriving motion from the main shaft of the carding-engine. The Cotter-cylinder is driven by a belt, g, passing over apulley, g', and deriving motion from the first worker of the carding-engine.

The feed-rolls A A are geared together by pinions lt hat one end and at the opposite end the lower roll, A', is provided with a spur- Wheel, h', which engages with a pinion, h2, on the wipe-and-pressure roll C. 0n the end of the roll A, at which are the pinions h h, there is a large spur-wheel, i, which is driven by a pinion, t', on a counter-shaft, i2. The shaft @"1 has a pulley, t3, and is driven by a belt, it, from the doier of the oardingengine.

In Fig. 4 I have represented my invention as embodied in an attachment for the delivery side of a wool-picker.

G designates a part of the picking-cylinder.

B designates the burr-cylinder, and E designates thc Cotter-cylinder, which are constructed like the cylinders before described, they being provided with toothed rings and interposed metallic packing-rings. They are rotated in reverse directions, as indicated bythe arrows.

D designates the guard or beater which knocks the burrs or extraneous matters into the burr-box.

H designates a brush which strips the wool from both the burr-cylinder and Cotter-cylinder and delivers it into any suitable receptacle. (Not shown.)

rlhe cylinders, guard,V and brush may be rotated at the desired speeds by any suitable mechanism, that here shown being suited for the purpose.

rIhe burr-cylinder B is driven by a belt, j. from the shaft of the picker-cylinder G, and the beater or guard D is also driven by a belt, j', from the same source. The shaft of the brush Hhas upon it a pulley, jz, which receives a driving-belt, j, from an overhead shaft, and a smaller pulley, j", from which passes a belt, j, to impart motion to the Cotter-cylinder E.

The several belts and pulleys are here shown only in dotted outline.
